iphone 将值从子类传递给超类
你好，我想在不使用对象的情况下从子类向超类传递一个字符串值。任何人都可以帮忙吗？我知道它与[self superView]有关。请帮忙
class c1
{
string s1
-(void) m1
{
}
}
class c2
{
// Here I want to call m1 and also pass values to s1
// without creating an object of the class c1
}
Hi, I want to pass a string value to the superclass from the subclass without using object. Can anyone please help. I know it has something to do with [self superView]. please help
class c1
{
string s1
-(void) m1
{
}
}
class c2
{
// Here I want to call m1 and also pass values to s1
// without creating an object of the class c1
}

他们与超类通信的关键字是
super。您可以像这样调用超类上的方法：They keyword to communicate with the superclass is
super. You can invoke methods on the superclass like this:你的问题需要更具体。
如果您使用的是 Objective-C（iPhone 应用程序的典型编程语言），那么您可以使用：
此调用采用关键字 super，它是对超类的引用，后跟您想要发送给超类的消息（Objective-C 方法）（Objective-C 的“调用方法”方式）。
如果您使用的是 C++（您的示例代码似乎表明了这一点），那么由于多重继承问题，我认为您无法调用超类方法。
You need to be more specific with your question.
If you're using Objective-C (the typical programming language for iPhone apps), then you can use:
This call takes the keyword super, which is a reference to the superclass, followed by the name of the message (an Objective-C method) you want to send to the superclass (Objective-C's way of "calling a method").
If you're using C++ (which your sample code seems to indicate), then I don't think you can call the superclass methods due to multiple inheritance issues.
